Transportation Engineering- II (CE-502) - Important Questions

Explain the types and stages of engineering surveys - map study, reconnaissance, preliminary and final location surveys - required for locating a new highway alignment.

Design the rate of superelevation for a horizontal highway curve of radius 400 m for a design speed of 80 kmph. State the IRC limits for maximum superelevation.

Explain the cross-sectional elements of a highway - carriageway width, camber, super-elevation, sight distances and extra widening at curves - with IRC recommended values.

A two-lane highway is to be provided with a horizontal curve of radius 300 m. The wheel base of design vehicle is 6.0 m and design speed is 80 kmph. Calculate the extra widening required at the curve.

Explain the step-by-step construction procedure of Water Bound Macadam (WBM) road including materials, spreading, compaction and finishing.

How is flexible pavement designed by CBR method? Explain with the help of sketch and design curve.

Explain rigid pavement and discuss its advantages and disadvantages over flexible pavement.

Explain the different types of joints in rigid pavements - expansion, contraction, construction and longitudinal joints - with objectives and neat sketches.

Explain the general principles of pavement design for flexible and rigid pavements including wheel load, subgrade and climatic factors.

Explain the scope and principles of soil stabilization for low-cost road construction. Discuss its requirements, advantages and uses.

Explain the objectives of road and street lighting and briefly discuss the various design factors involved in road lighting.

The basic runway length required under standard conditions is 2000 m. The airport site has an elevation of 300 m and reference temperature of 32 deg C. The effective gradient is 0.4%. Calculate the corrected actual runway length by applying elevation, temperature and gradient corrections as per ICAO.

Explain the various aircraft characteristics and how they affect the planning and design of airports and runway alignment.

Explain the geometrical elements of airport runway and taxiway including width, gradients, sight distance and clearances. Discuss the pattern of runway capacity.

What is zoning? Discuss the different zoning regulations for airports with the help of neat figures.

Draw a neat sketch of runway lighting and explain its different parts in detail.
